The remains of an escaped convict are found in a residential sewer, but an examination of the sewer pipes indicates that the murder occurred within prison walls. Brennan insists on solving the crime - despite Booth's pleas for her not to overexert herself - and the expectant couple experiences a very untraditional arrival of their baby daughter.

When a corpse is found at a landfill, dyed in a blue substance, intern Arastoo Vaziri discovers a method that helps eliminate postmortem damages to the corpse, which leads the team back to a hair salon where the victim worked. Meanwhile Bones is feeling uncomfortable in her post-baby body, so Booth decides to do something special to boost her self-confidence.
